Does your area put out dangerous driving conditions warnings? If so, maybe you could make an arrangement with him before it snows that if a certain warning is given, you should be allowed to go home for safty sake? Then when it happens, he will be less likely to decide that his inconvience of the moment is more important than your safety.
Or ask him to drive you home in really bad weather if you are sure he is a good enough driver? Maybe the long scary drive home when he's not sure he can make it will prove enlightening?
